The Yamaha XT X 660 is a versatile adventure motorcycle, capable of handling both paved roads and more challenging terrain. However, over time, the original brake discs tend to suffer accelerated wear, compromising braking precision and safety on demanding roads. With Brembo Serie Oro brake discs, you'll recover that decisive and modular braking response that characterizes this splendid machine.
The front kit 78B40894 (320mm diameter, 4.5mm thickness) and rear kit 68B407H8 (245mm diameter, 5mm thickness) were developed specifically for the XT X 660 from 2004 to 2009. Each disc is forged and tempered according to Brembo standards, ensuring thermal consistency and long-term reliability.
The lightweight aluminium bell reduces unsprung weight on the wheels, improving overall ride dynamics. The peripheral drilling enables efficient heat and gas dissipation generated during repeated braking, maintaining consistent performance even under thermal stress. Pairing with modern Brembo pads guarantees superior grip and modulation without compromise.
The discs are TÜV approved and road-legal throughout Europe. Installation is drop-in type: no frame modifications, no technical inspections required. Direct replacement of original equipment, no mechanical intermediaries.
Every Brembo disc is 100% Made in Italy and covered by 2-year warranty. Discover in a few clicks how to transform your XT X 660's braking performance by visiting M4Tuning.com and trusting those who know motorcycles.
